1 Introduction

The Free Protocols Foundation (FPF) is a non-profit organization and independent public forum dedicated to the support of
patent-free protocols and software. The FPF views software and protocol patents as being generally detrimental to the industry
and the consumer, and part of the FPF mandate is to oppose exceptionally harmful patents when they appear. For more
information see the FPF website at http://www.freeprotocols.org.

Research in Motion (RIM) has recently made a patent assertion which we regard as an egregious example of patent law
abuse, and exceedingly harmful in its potential effects. The following is a statement of the FPF position regarding this patent,
and our intended actions to oppose it.

2 Research in Motion (RIM) and BlackBerry

Research in Motion (RIM) is a Canadian wireless technology company based in Waterloo, Ontario, Canada.

Among other things RIM manufactures and licenses BlackBerry, a popular wireless handheld e-mail device. BlackBerry is
a closed, single-vendor e-mail system, based on a set of proprietary protocols. For details see the BlackBerry website at
http://www.blackberry.net.

3 RIM’s Patent Assertion

In April 2001 RIM was granted U.S. Patent # 6,219,694, entitled System and method for pushing information from a hostsystem to a mobile data communication device having a shared electronic address. The complete text of the patent is available
at the FPF website; to view the patent in PDF format visithttp://www.freeprotocols.org/usPatents/06219694.pdf.

The patent describes a method of directing e-mail to wireless devices, while maintaining mailbox synchronization with a
desktop e-mail system. The described method is a basic element of the functioning of various existing mobile e-mail systems,
including the BlackBerry system.

4 FPF Position on the RIM Patent Assertion

The Free Protocols Foundation views the RIM patent assertion as an extreme example of patent-law abuse. This is
because:

The patent is based on methods and processes which were previously known and implemented, and there is
ample prior art to demonstrate this. RIM’s claim that these processes are novel is therefore false.

The patent covers an aspect of mobile e-mail that is so fundamental that if it goes unchallenged, it will have the
effect of hobbling the wireless and mobile e-mail industry.

The patent is particularly noxious because of the very large scope of its claims. Note that mobile e-mail is not simply
another generic product or service – it is an extremely large-scale interconnected system, whose functioning is of profound
importance to business and society. It is inappropriate and dangerous for any one company to have exclusive control over
something of such enormous scope and significance.

Yet this patent purports to provide RIM with precisely this control. RIM’s patent claim is so broad and general that if it
remains unchallenged, it will restrict a major class of mobile e-mail services to a single closed system under the exclusive
control of RIM, to the severe detriment of the mobile e-mail industry and society at large.

5 Actions and Remedies

The Free Protocols Foundation intends to participate in fighting strenously against this patent by means of the following
activities:

By assisting in demonstrating the invalidity of the patent

By supporting legal challenges against the patent

By endorsing and publicizing Operation WhiteBerry, a patent-free alternative to BlackBerry

By pressuring RIM to drop their current patent assertion, and to renounce any future assertion on the basis of
this patent

Should these measures fail to persuade RIM to drop their patent assertion, by encouraging a consumer boycott
of the BlackBerry system

5.1 Demonstrate Patent Invalidity

Those whose interests are being injured by the patent will certainly wish to challenge it. A key element of this challenge will be
to demonstrate that the patent is invalid on the basis of prior art. We believe that ample prior art exists which will show
clearly that the patent is based on ideas which have been previously known, subjected to public discussion, and
implemented.

The basic requirement is to identify and make public the appropriate prior art. The Free Protocols Foundation is assisting in
this effort by providing a public forum for discussion and commentary, and by acting as a central clearing house for
information relating to the patent.

For this purpose the FPF has established and is hosting the public mailing list RIM-6219694@lists.freeprotocols.org. Any company, organization or individual may participate in this effort by
submitting commentary or information to this mailing list. To join this mailing list, visithttp://www.freeprotocols.org/joinFreeProtocolMailingList/main.html.

The following is a list of known development activities, each of which predates the RIM patent, and in which the same
processes as represented in the patent claims were put into practical implementation. The documentation and
discussion records relating to these activities are therefore extremely likely to yield appropriate examples of prior
art:

Various combinations and integrations of IMAP modes, including the concepts of disconnectedness and
synchronization. While the claims represented in the RIM patent are not a formal part of the IMAP specification,
many of the same methods and processes are clearly alluded to in the specification. Furthermore, many of
those same methods and processes were discussed and implemented by the IMAP protocol designers during the
protocol development process. Such discussions took place on a number of IETF and other mailing lists.

Various combinations and integrations of FetchMail, ProcMail, dotForward, mail robots and mail header
rewritings. These components have been linked together by many Unix users to produce practical
implementations of the same claims as represented in the patent.

The Limited Size Messaging (LSM) development work published and demonstrated at the CDPD Forum in
1995.

The Lightweight & Efficient Application Protocols (LEAP) development work published as RFC 2188 in 1997,
and RFC 2524 in 1999; also the relevant mailing lists.

The development and commercial marketing of Mobile Messaging products such as the RadioMail wireless
messaging service by RadioMail Corporation (initially led by Geoffrey Goodfellow), dating back to the early
1990s.

Proprietary mail synchronization capabilities of commercial systems such as Mail on the Run! and numerous
others.

The role of the Free Protocols Foundation consists primarily of the assistance and facilitation role described above. We
invite and encourage other interested parties to identify specific examples of prior art by researching the archival records
relating to the above activities. We especially request and encourage the original participants in those activities to step forward
and assert their prior implementations of the RIM patent claims.

5.2 Support Legal Challenges

In general, the Free Protocols Foundation supports legal challenges to software patents by providing its technical expertise
regarding patent issues to companies who may be challenging patents in the courts.

In the present case, the FPF is ready to lend its support to Glenayre or any other company that mounts a legal
challenge/defense against the RIM patent. Any company or organization wishing to avail itself of this assistance should contact
the FPF directly at info@freeprotocols.org.

5.3 Operation WhiteBerry

The same mobile e-mail functionality as BlackBerry can be implemented in the form of a completely open system, based on
existing technologies and protocols. This open equivalent to BlackBerry is called the WhiteBerry mobile messaging
solution.

The WhiteBerry solution is based on a set of patent-free mobile messaging protocols called the LEAP protocols. Under the
WhiteBerry solution, mobile messaging functionality is provided by a multi-vendor series of products and services, and the
necessary industry-wide interoperability is guaranteed by the openness and integrity of the underlying protocols. For more
information on the LEAP protocols see the LEAP Forum website at http://www.LeapForum.org.

A complete description of the WhiteBerry solution is provided in a white paper entitled Operation WhiteBerry. OperationWhiteBerry was written prior to, and is independent of, the emergence of the RIM patent issue. It was first published and
remains available on the LEAP Forum website athttp://www.LeapForum.org/operationWhiteberry/index.html.

One of the general strategies by which the FPF opposes patented software is by supporting patent-free alternatives. Since
Operation WhiteBerry describes an open, patent-free alternative to the patented BlackBerry system, it is directly aligned with
this strategy. This paper is also fully consistent with FPF goals, and with the FPF Policies & Procedures described at
http://www.freeprotocols.org/freeProtocolProcess/main.html.

The WhiteBerry solution is radically different from the BlackBerry system. WhiteBerry is not a single static messaging
solution; rather, it is a highly mutable meta-solution. That is, any particular WhiteBerry implementation is created by
integrating together an appropriate set of components, so as to achieve the particular functionality desired by the systems
integrator or the end user.

The components that go into any given WhiteBerry implementation may be drawn from a large family of components
which includes the EMSD protocol engines, FetchMail, ProcMail, mail forwarders, and various others. Each of
these components is independent, freely available, useful in its own right, and entirely unrelated to the RIM
patent.

Because of this inherently component-based nature, the WhiteBerry solution is exceedingly resistant to the RIM patent
claim, and indeed to patent infringement claims in general. By making all the necessary components freely and publicly
available, WhiteBerry provides systems integrators and end users with a variety of methods and strategies to circumvent or
nullify invalid patent assertions.

5.4 Apply Pressure to RIM

Patent # 6,219,694 is a blatant attempt by RIM to lay exclusive claim to the entire mobile e-mail industry. The patent is
fundamentally invalid, and cannot withstand technical scrutiny or legal challenge. The lawsuit against Glenayre, and the effort
that the industry must now undertake to overturn the patent, are a huge waste of time and energy. In the meantime RIM’s patent
assertion can only be detrimental to the mobile e-mail industry, by inhibiting free and fair competition, and by depriving the
end-user of the benefits thereof.

It is in everyone’s interest for RIM to cease and desist in this patent assertion. We therefore urge RIM to do the right thing:
abandon their current attempt to assert this patent, and renounce all future attempts.

5.5 Boycott RIM’s BlackBerry System

If other measures fail to have the desired effect, and if RIM’s continued prosecution of its patent assertion begins to cause
damage to the mobile e-mail industry, then the FPF intends to organize and encourage a consumer boycott of RIM’s
BlackBerry product.
